To (155 whom 2'6 may; concern:

it known that 1, JOHN l /icllaimmnr, a citizen oi the United States, and a r dent of Stamford, in the county of airfield and Slate of ilonnecticut, have invented certain new and useful improvements in Machines for Printm hilaster-bheets for 1 r b JL lype-iiriier Operators, &c., or which bh following is a specification. I

This invention relates to machines for producing master-sheets adapted for use in connection with automatic mechanical typewriter operators, mechanical musical instruments, etc.

A n1aster-shcet for a typewriter operator is provided usually along itslongitudinal center with rows of feed perit'orations adapted to engage feeding projections on the feed roll of a perforating machine employed to perforate the sheet to proyide typewriter keyoperating perforations therein, the said operating perforations being formed subsequently to the formation of the feed perforations. The operating perforations are formed in accordance with the matter to be typewritten, each operating perforation occupying a diiierent position lengthwise of the sheet from all the others. Heretoforc, the sheet has not been provided with designating characters by which the operating perforations may be read, so that the printed matter which they are desi ncd to produce cannot be readily determined by a quick inspection of the sheet.

My invention has for its object to provi .e a machine adapted to apply to the sheet, printeo matter which will enable the operating perforations subsequently formed on the sheet to be easily read, the printed matter being arranged in a definite and unvarying predetermined relation to the feed perforations of the sheet, and to the spaces intended for the operating perforations siibsequently formed.

The invention consists in the improve ments which I will now proceed to describe and claim,

section the punching mechanism hereinafter described; 6 represents a section on line (3 b of ig. 1; Fig. 7 represents a View of a fragment of the centrai portion of a Inaster-sheet and shows the printed characters impressed thereon by the embodiment of my machine shown by the preceding fi ures.

The same reference characters in icate the same parts in all the figures.

The supporting frame of my machine includes a base 12 having a bed 13 over which the paper sheet 14 to be printed is drawn by a feed roll 15 journaled in bearings at one of the machine. Said feed roll is pro vided at its central portion with radial feeding pins 16 adapted to enter perforations 17, (Fig. 7) formed along 'the'central portion of the sheet 14. Said perforations may be formed in the sheet before it is acted on by the machine of my invention, but i prefer to provide the machine with punching mechanism adapted to form the perforations 17, as hereinafter described. The engagement of the feeding projections 16 with the feed perforations l? or" the sheet causes a positive engagement between the feed roll and the sheet, so that the sheet cannot move independently of the feed roll, and so that the printing couples which are geared to the feed roll hereinafter described, will do their work accurately with relation to the said perforations 17.

l8 and 13) represent the members of a printing couple arranged to bear on opposite sides of the portion of. the sheet which is located o'ver the bed 131 The member 19 is a bed roll located in an opening in the bed 13, its highest point being substantially flush with the surface of the bed. The member 18' is a typewheel provided with raised printing characters 21 which, in a machine for printing master sheets for typewriter operators, will include the letters of the alphabet and other characters usually printed by ordinary typewriters. The portion of the member 18 shown by Fig. l is provided with type to print the letters of the alphabet, the types being arranged in peripheral rows and each row including types of the same character, the types of each row difi'erin from thoseof the other ows, as indicate so that'the operation of rinting couple on the sheet causes the p itlng of corresponding letters on the she-st in rows extending lengthwise thereof,

as indicated by 7. The types of the member 18.are inked by an inking roll 22 located above the member 18.

The embodiment of my invention here shown include additional printing couples 23 and 25, 26. The member 24: is prowith longitudinal radial rule printingfprojections 27 adapted to print transverse lines on the sheet 14:, and the member 26 is provided with peripheral circular rule projections 28 adapted to print longitudinal lines on the sheet 14:, the said transverse and longitudinal lines intersecting and subdividin the sheet into squares. The several printing couples are geared together and to the feed roll and operated in unison, as here inafter described, the arrangement being such that the characters printed by the member 18 occupy an accurate predetermined relationship to thelines printed by' the members 24 and 26, the printed characters being preferably within alternate squares extending lengthwise of the sheet, as shown by Fig. 7

30 represents a driving be continuously rotated by any suitable means.

31 represents a fixed punch bed or die I which mayv form a part of the bed 13 and is located between the printing couples and the feed roll.

32'represents a gang of punches attached to a reciprocatingacarrier 33 which is movable in a fixed vertical guide 34, and isreciprocated by an eccentr1c35 afiixed to the driving shaft 30, and a strap 36 surrounding said eccentric and pivoted at 37 to the punch carrier 33. The eccentric and strap are caused by the rotation ofthe drivorganized to cause an accurate or predetermined relation between the printedimat ter and the feed zperf orations 17, saidrnechanism in the embotlili'fentpf my invention here shown being organized asfollows'i 38 represents a mutilated gear attached to the driving shaft 30 and preferably composed of a disk having a single gear tooth 39. 40 represents a gear wheel having elongated .teeth provided with inwardly. curved outward faces 41 and separated by notches 42, each adapted to engagethe gear tooth 39. The gear 40 is mounted to rotateon a stud or bearing 44, and to it is attached a spur gear iowhich forms a part of a train of shaft which may larly for use in mg machine and the automatic typewriter which imparts motion from the driving shaft to the feed roll and tothe members of the several printing couples. The gears 38 and to constitute a well known form of segmental intermittent feed motion, the continuously rotated or driving gear 38 having an operative movement during only a small part of a complete rotation, the movement during a greater part of a rotation being a dead movement. The recessedfaces 41 of thegear 40 engage the periphcry of the disk portion of the gear 38 so that the gear 40 is locked during the dead movement of the gear 38'. The spur gear a5 is attached to the gear 40 and is rotated gearing intermittently thcrb said gear l5 being"- connected with the feed roll 15 by an intel-mediate gear 1-6 meshing with a gear 47 on a shaft 1-8 of the feed roll. To the shaft 48 is attached a smaller gear 49 meshing with a larger gear 50, which in. turn meshes with a smaller gear 51 attached to the shaft 52 of the printing couple member 25. The gear 51 meshes with a gear attached to a shaft 54 of the printing couple member 26. The described gearing is organized to rotate the printing couple members 25 and 26 in the directions indicated by the arrows in Fig. 4.. The shaft 55 of the inking roll which supplies the printing couple member 26 is provided with a gear 56 meshing with the gear 53. The gear 51 attached to the lower printing couple member 25 is con nccted by a gear 57 With a gear 58 attached to the shaft of the printing couple member 23. The printing couple members 23 and 2a and 19 and 18 are geared together in the same manner as the printing couple members 25 and. 26. and the gears ofthe lower couple members 23 and 19 are connected by an intermediate gear 59 so that the members of each couple are rotated in unison in the directions indicated by the arrows in Fig. 4. I It will be seen that the described mechanism provides for the accurate location of the printed character on the sheet with reference to the feed perforations 17 formed therein and to the squares printed on the sheet by the couples 23, 24,25, 26, so that when the sheet is subsequently passed through a perforating machine to receive operating perforationsthe latter will be ac curately located with reference to the printed squares and characters and to the feed perforations. Again, when the perforated master-sheet is applied to a typewriter operator, the operating perforations will be caused to occupy the desired relationto the parts of the operator controlled thereby in actuating the typewriter keys. A mastersheet having feed perforations and printed matter, as herein shown, is adapted particuconnection with the perforatoperating machine set forth in two applications for Letters Patent of the UnitedStates filed by me concurrently herewith, Serial Nos. mania and 676 The WPer plied to the machine may be stored on a magazine roll 62 supported by "bearings 63 at one end of the base 12'. p f

It is obvious that if the sheet is is per forated before it is acted on by the printing l0 mechanism, the punching mechanism above described being omitted, theintermittent feed motion may be dispensed-with and the feed roll and printing couples continuously rotated. This may be accomplished by gear- 15 ing the driving shaft 31 directly to thetrain of gears which transmits motion. therefrom. is also obvious that the printing couples which print the longitudinal and transverse lines, or either of said! couples ma be omitted so that only the characters printed b- {the member 18, or only said characters s; one setof lines will be printed on the 7 men in the printed sheet, they'willbear a 7 -',crmined relation to the printed charthereon. For example, a, perforation intended to cause the printing of the letter S by a typewriter will be located in a en operating perforations are spa e between two printed letters of the c S row, Fig; 7, while a perforation intended to cause the printing of the letter T will be located in a space between two printed letters of the T row. The letter 3-5 or character represented by each operating perforation is therefore clearly indicated by adjacent printed characters on the sheet. The feed perforations 17 are formed in the same transverse row of squares as the print- 40 ed characters, but are smaller than the latter, so that the characters are not rendered illegible by the perforations.
